Title: Improvements in or relating to vehicle braking systems
IPC: B62D11/08
Filed: 1946-05-29
Abstract: 619,874. Vehicle brake mechanism. FERGUSON, Ltd., H., and FERGUSON, H. G. May 29, 1946, No. 16404. [Classes 79 (ii) and 79 (v)] [Also in Group XXXIV] A vehicle braking system for brakes of the kind applied by rearward rotation of a control member or shaft comprises a forwardly projecting pedal supported for pivotal movement at its rear by the control member and reaction means so associated with the pedal that depression of the pedal and forward rotation, i.e. rotation in the direction of a wheel on a forwardly moving vehicle) causes rearward rotation of the control member. As shown in Figs. 1, 2 and 4, applied on an agricultural tractor, each control shaft 3, carries fixedly by means of a screw clamp and a key a split boss 19 having a downward web 22, at the bottom of which is a longer boss 23 in which is rotatably mounted a short shaft 7 which carries fixedly at either end a forwardly projecting pedal 4 and an arm 8. Pivoted at 7a on the arm 8 is a rod 9. An upper projection of the arm 8 is engaged with the front side of the boss 19 on the shaft 3. The forward end of the rod 9 is pivoted to an arm 10 fixedly engaged at one end of a transverse shaft 13 passing through or under the tractor body. At about the midpoint of this shaft 13 is fastened by means of spot welds 18 a tube 14 extending to one side of the shaft so that the torsional deflections of the shaft 13 will not upset the balance between the two brakes. Fixed to one end of the tube is the coupled pedal 15 which passes under a foot-rest 16 attached to the tractor body. A pivoted latch or pawl 25 may be carried upon the coupled brake pedal 15 which is adapted to engage a ratchet plate for the purpose of keeping the brake on. This pawl may also be so weighted or urged that it normally tends to remain in an inoperative position. Depression of one of the individual brake pedals 4 would but for the foot-rest 16 turn the lower end of the arm 8 rearwardly. Due to the foot-rest 16a, toggle action takes place about the shaft 7, rotating the shaft 3 in a rearward direction, thus applying the brake in the selected rear wheel. To operate both rear wheel brakes simultaneously, the pedal 15 is depressed moving the pivots 7a forward. Rotation about the shaft 7 is stopped by the upward projection of the arm 8 on the shaft 3 and so the shafts 3 are rotated rearwardly and the brakes applied. In a modification, Fig. 7, each individual pedal 26 is pivotally mounted at a point 27 on the arm of a bell-crank 28 clamped on the shaft 3 and the rearward part 26a of the pedal engages the under part of the rear axle casing 29. Upon depression, the pedal 26 reacts on the axle casing and rotates the shaft 3 in a rearward direction, thus applying the brake. Lost motion effect during this operation upon the coupled brake mechanism is gained by the rod 9 being connected by a pin 30 and a slotted jaw end 31 to an arm 32 fixed on the shaft 3.

Title: Improvements in apparatus for registering the consumption of motor spirit and the like
IPC: G01F9/00
Filed: 1920-06-22
Abstract: 145,510. Mairich, H. June 17, 1914, [Convention date]. Partitioned-chamber type.-In apparatus for determining the consumption of motor spirit or other light fluid a meter operating on the principle of the wet gas meter is adapted to drive two counting-mechanisms for indicating the total consumption and the amount of fluid left in the tank, so arranged that the former is stationary while the latter is being set by hand to show the amount of fluid in the tank after it has been filled, during which operation a spring, facilitating the action of the counting mechanisms, is re,- wound. A drum 1, Fig. 3, with spirally-formed scoops drives a spindle 3 through a crank 2 and through a pinion and wheel 4 carrying a ratchet device 6 drives a spindle 7 and thereby the counter 5 which indicates the amount of fluid left in the tank; a wheel 9 which gears with the wheel 4 is adapted to drive the consumption counter 10. The ratchet device 6 allows the spindle 7 to turn independently of the wheel 4 to enable the counter 5 to be set, which is effected by pressing in and turning a knob 11 the spindle of which carries a wheel 12 adapted to gear with another wheel on a spring drum 8 which is thereupon rewound. It the device is disposed in the pipe and the fluid is fed to the meter under pressure from a tank A at a lower level the meter is fitted with a chamber E into which the fluid to be measured falls and from which it is fed by a pipe F to the hollow shaft G of the meter drum J, thence passing to the place of consumption C. On replenishing the tank the motor spirit only flows back to the tank, the trapping liquid being retained in the bottom of the chamber E; the trapping liquid is forced back again when the pressure is restored before any of the fluid to be measured can pass into the drum.
